Well, you’re definitely in a much better position just by posting the question and getting all these responses. Something I should have done a year and a half ago.
I ended up with a close relative, on my couch, for 8 – 9 months. All day, every day, living on my couch. I live in a 500 – 600 square foot apartment. It was supposed to be a couple of months, max. It took a tremendous toll on me.
Because of who this particular relative was, I didn’t think it was necessary to lay down the most obvious of rules/duties. I was wrong. Had I done what these folks are suggesting it would have gone much better for me – and, I believe, him as well.
Be firm and be consistent. You’ll both appreciate it in the end. Good luck with that.
